I beat easy after 3 tries! :P (I had 11 lives left too!)
Not too good at it, but I figured out a good layout once i got the game a bit better.
Did you do a maze type thing?
I tried a different type of strategy the other day. I just put up three different towers and maxed their upgrades as soon as possible and then later put up slow towers and stunners.
Faster, easier method and doesn't require as much time and effort
Didn't work too well on medium though
